主题中讨论的其他器件：SN65DSI86您好！
我将 sn65dsi86 evb 连接到 im8mp EVB。
我正在尝试使用 mipi_DSI 时钟(DPPLL_CLK_SRC = 1)。
引导时没有出现任何错误、但显示器无法初始化。
使用我通过27M 时钟定义的"REFCLK"时、显示器和电桥工作正常(目标板上没有 REFCLK、因此不是选项)。
DTS 节点：
mipi_dsi: mipi_dsi@32e60000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,imx8mp-mipi-dsim";
#clock-cells = <1>;
reg = <0x32e60000 0x10000>;
clocks = <&media_blk_ctrl IMX8MP_CLK_MEDIA_BLK_CTRL_MIPI_DSI_PCLK>,
<&media_blk_ctrl IMX8MP_CLK_MEDIA_BLK_CTRL_MIPI_DSI_CLKREF>,
<&clk IMX8MP_CLK_MEDIA_DISP1_PIX_ROOT>;
clock-names = "cfg", "pll-ref", "refclk";
assigned-clocks = <&clk IMX8MP_CLK_MEDIA_MIPI_PHY1_REF>;
assigned-clock-parents = <&clk IMX8MP_CLK_24M>;
assigned-clock-rates = <24000000>;
interrupts = <GIC_SPI 18 IRQ_TYPE_LEVEL_HIGH>;
power-domains = <&mipi_phy1_pd>;
status = "disabled";
port@0 {
dsim_from_lcdif: endpoint {
remote-endpoint = <&lcdif_to_dsim>;
};
};
};
sn65dsi86: sn65dsi86@2d {

dsi-clocks;
clocks = <&clk IMX8MP_CLK_MEDIA_MIPI_PHY1_REF>;
//clocks = <&mipi_dsi 0>;
//clock-names = "refclk";
no-hpd;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
sn65dsi86_in: endpoint {
remote-endpoint = <&dsi0_out>;
};
};
};
};
};
请协助、
谢谢！
